To all whom ilmay concern:

Be it known that I, EENPJ Barium, chemist.

of the Swiss Rcpu'blic, rcsiding at Mu'lliouse, in Aimee,

German Empirc, have invented new and useful Improvcnlcnts in the Production oi Lrown Shades on the Fibor, of which mi following is a spi. :zition.

Attempts to produce brown shailcs i. of paraphcnyicnmiirtmin on ziic libcr in a manner similar to that in which aniiiu black is produced, have hitherto met with no tcclinical success, in misc, when the il \"(il'0CiliOl'l i in oxid' d i) means of a chlorate and an oxygcn carricr, in particu ar a vanadium salt. shades arr. obtained which are not file and, the fiber in corroded and won- I have now s can bo "obtained if, wlicn n11 nug USCG! pun-phony mmzuin hyflii'mfili llifi, H grout port, or iii.- W 10 of the hydrochloric acid bc neutralized, W iffii in be done 2m in stance by means of sodium acetate, or of sodium forinate, or of nikaii.
